Answer 1

Answer:

On bringing both the spindle and the stud together, if the zero mark of the circular scale is below the baseline of the main scale, the zero error is said to be positive. Zero error = The number of circular scale division which coincides with the baseline x L.C. The value of this error is always positive.
